e) Start condition generation and address transfer
To change the transfer direction or slave, a new cycle must be executed after the
current cycle is completed by generating a stop condition or invoking another start
condition. To generate another start condition, the RSRT and BCM1 bits of MCTL0
should be set after a 4us delay to keep the set up time of the start condition.
The next data transfer cycle is for read, so reset bit 3 (MDIR). To enable the start
action, set bit 7 (ACT) of MCTL0.
